When breaking in the Kazz diff. I drove in figure 8's for 1/2 hr.
Never exceeded more that 20-25 kms per hr.

After I noticed that the inside of exhaust tip is white. I know it is usually kind or light tan or brown.

Should I be concerned...
could this be coolant? jc.

The only time i have seen white or light gray soot on the inside of the exhaust is when running race gas, like higer than 104. Other than that I don't know.

Back in the "good ol' days" of the 60's and early 70's, a white exhaust was a good thing, as it showed the engine was tuned just right, and the white was left from the lead in the leaded fuel back then. Hell, you'd see a bunch of guys at filling stations with big *** grins COMPARING the 'whiteness' of their exhausts....I **** you not!

But white on a modern car? Not, good, thinks I.......perhaps a bit of coolant.......

Thanks Dr.Wankel

I remember I had about 1.5 gallons of C16 left in the tank. (From the Dragstrip) I guess this was being burned off. I should have mixed in some more unleaded 92 pump gas. I probally had 4 gallons of 92 pump gas mixed in with the 1.5 gallons of C16.

Could I have fouled my plugs running the C16.

Thanks again... jc
